The primary purpose of this annual directory is to list all local agencies providing free public elementary and secondary education in the United States and its outlying areas. Included are agencies that provide general or both general and specialized education, but not those that provide only specialized education. The directory does not include area vocational-technical training systems nor does it include any area school systems that provide only special education. "Local" as used here denotes those agencies closest to the actual operation of the educational programs. Where administrative services are performed for more than one school district by a common superintendent, the resulting supervisory union is listed in addition to the local school districts. The main body of the directory lists, in alphabetical order by state, the following information for each system: name of unit, mailing address, county name, grade span, number of pupils, and number of schools. Also included are summary tables showing: (1) the distribution of operating local public school systems and numbers of pupils by system size; (2) the number of such systems by grade span and size, by grade span and state, and by school system size and state; and (3) the number of operating and nonoperating public school systems by state or other area.
